ABOUT OUR BELT DRIVES
1. Less Maintenance- Belts don’t need to be lubed regularly, they don’t rust, and if they get dirty just hose them down.
2. Durability- Belts wear slowly and evenly, lasting at least twice as long as chains. Belts can also handle the torque of a motor on an e-bike better than chains, leading to longer wear life.
3. Clean- With no lube, there's no need to roll up your pant legs when you’re headed to work. Don’t worry about getting your hands dirty when tinkering with your belt.
4. Responsive & Smooth- With no belt stretch you feel the direct transfer of power in every stroke. Feel like you’re gliding on your ride.
5. Lighter- Belt drives are about half the weight of chain drives. The belts themselves are about 25% of the weight of a chain, and the sprockets are only slightly heavier.
6. Quiet- The belt drive is so quiet you’ll forget it’s even there.
Belts don’t work with a derailleur based shifting system. If you want multiple gears, you would have to pair it with an internally geared hub or gearbox. We do not sell these systems, but we can recommend what would work best for you. You can also check out our blog on How to Choose an Internally Geared Hub.
Belts will last at least twice as long as chains, but often 4x as long depending on care and how you ride it. Some riders have already put as much as 20,000 miles on one belt drive system. Wear life is shorter on an e-bike, but still outlasts a chain on an e-bike.
We do not. With our fully optimized tooth profile on our sprockets, we are able to run at lower tension, making installation a breeze.
A perfectly aligned chainline when installing your kit is crucial and helps keep the belt on. The guide flanges on the Split Belt™ also helps keep the belt from falling off the sprockets. Some rear cogs do not have guide flanges and a little bit (~2mm) of drifting is normal.
We use carbon fiber reinforced, nitrile rubber belts that are stronger than most belts on bikes currently.
PRODUCT RANGE AND COMPATIBILITY
Currently, we offer compatibility with most of the major internally geared hubs on the market, including Shimano's Alfine, Nexus, Sturmey Archer, Enviolo, standard freehubs, etc.
We are also compatible with most of the major motor manufacturers on the market, including Bosch, Bafang, Shimano Steps, Brose, etc.
Yes, if you have the belt drive specific motor unit. The standard electronic motor unit/shifting mechanism near the rear cog does not allow sufficient room for our cogs if you have the standard unit meant for chains. The belt drive specific unit is model MU-UR510 .
OEMs reach out directly for solutions.
A product for Dealers and customers is currently in development.
Yes! We believe belt drives are the best option for E-bikes. Many E-bike users wear through their chains frequently and our belt drive will provide a longer lasting solution.
Our system is compatible on mid-drive motors that have a maximum continuous torque of 90Nm. That covers most of the street-legal bikes on the market.
We are not. Our belt drives use a different tooth profile and tooth pitch.
Chain teeth x 1.59 = Belt teeth.
For example, our 72T front beltring is equivalent to a 45T chainring (72/1.59 = 45.28).
Or, a 40T chainring is roughly equivalent to our 64T beltring (40 x 1.59= 63.6).
It does! We custom cut our Split Belt to length and can provide belts for tandems, long-tails, cargo, etc. Just provide an exact measurement of your chainstay length (spindle to rear axle) and we will do the rest.
PURCHASING, SHIPPING AND INSTALLATION
OEMs can order directly from us by emailing us at email@example.com.
Dealers can order directly from us or from one of our international distributors.
Customers can order from a local Dealer. If your local Dealer does not carry our product, have them reach out to us and we can set something up.
If you have adjustments in your dropouts or bottom bracket, you will want to adjust them so they provide the minimum chainstay length. Once adjusted, you will want to measure from the crank axle to the rear wheel axle.
Here is a video on how to measure your minimum chainstay length.
Yes. We sell a bike shop specific, Pro Riveting Tool. The Pro tool can install up to 100 belt systems.
OEMs have the option of using a factory level, pnuematic riveting tool that automatically installs and rivets the pins.
Please contact us at firstname.lastname@example.org for information regarding your location, or contact your local bike shop to reach out to us and we can get them a kit.
